Magnetic Compass Deviation vs Variation - AeroGuard Flight Training Center

Learn the differences between magnetic deviation and magnetic variation when reading the magnetic compass in an aircraft. With an understand of these concepts, you can better understand the impact these have on your magnetic heading and true heading.

Magnetic Course is what helps you decide what altitudes to choose from above 3000 feet (000-179: odd + 500; 180-359: even + 500)

Thank you, Kafa, we appreciate the comment!

Thanks for this video

Thanks !

thank you !

[@wildstylejewelry3743]

equivocal, equivalent, same thing... does it vary in Europe? Thnx

[@cockpitlife737]

Sir what you think which book is best for cpl exam

[@whiteheartt]

I watched this one among others because the length of the video is 737 so I thought thats a sign lol Thanks for your great explanation 👍

[@flyaeroguard]

Must be a sign! Thanks for the feedback!

For deviation error, if you have two planes that are the same, for example two Piper Warriors. What causes the deviation degree to be different if they carry the same equipment?

[@flyaeroguard]

Hi Kevin, thanks for your question! Deviation is affected by magnetic fields in the aircraft, caused by electrical current flowing through wires and in instrumentation. While the deviation could be different due to wiring harnesses being in slightly different locations or different instrument placement in the cockpit, the important thing to know is that the compass deviation card is always required and you should follow the information on that card while navigating using the magnetic compass!

Thanks for another informational video Eric. Can you please explain how we find the degree of variation for our route? Thanks.

[@flyaeroguard]

Hi there! Please visit kzbin.info/www/bejne/n2THc3ifa8h6las for assistance with this. Thank you!

[@josephleon5632]

Look for the magenta dotted line and in that line should be a number with a west or east variant if east (regardless of what direction you’re flying) you’ll subtract and vice versa if it’s west but add if west

[@cn9936]

@@josephleon5632 thanks for responding. Thank God I passed my written PPL test last month! I appreciate it.

10 degrees over what distance?

[@flyaeroguard]

Hi Jim. 10 degrees in this example is just referring to the difference of True North and Magnetic North so 10 degrees would stay the same for the entire distance. If someone is travelling from East to West or vice versa, the variation would either decrease or increase depending on which direction they are heading

KDVT!

Good spot! It is Deer Valley Airport!

The magnetic compass, good for a boy scout in the woods, terrible for an airplane.

[@TheDoodoo42]

West is best. East is least.
